It may be good PR. Baker Hughes has not only been a leader in oilfield technology, but has also been a leader in the inexact science of producing benign media coverage. The company says it will disclose the identities of all the chemicals it uses, but not the exact amounts or proportions. This move might also be a shrewd way of getting a jump on the inevitable, ahead of possible EPA mandatory disclosure requirements.

When the fertilizer depot in West, Texas, blew up, some schools were damaged beyond repair. Fortunately, none of the kids died. But it raised an issue that has been obvious — and too often ignored by news media — for years.

The DEP acquiesced at the time, but later cited Chevron for nine violations at the site.
